Specification forming part of Letters Patent No. 36,456, dated September 16, 1862.

To all whom it may concern:

Be it known that l, G. FREDERICK' DEGE- LOW,of Bethlehem,Northampton county, StateA ofdennsylvania, have invented a newv and Improved Mode of Imitating the Grain of Various Woods on Paper or other Material; and I do'hercby'declare that the following is a full and exact description thereof, reference being had to the accompanying drawing, and to the lettersof reference marked thereon.

The nature of my invention consists ofimitating the peculiar porous appearance of the grain of various woods on paper, leather, oilstitute what is called4 the grain of the w'ood.. The veins,l as well as these pores, are of darker color than' the rest o`f the surface. For imitating this peculiarity of the. grain of Woodsto Wit, this porous appearance-I use the following processvwhieh effects the purpose ina very rapid, eicienmand complete manner.

I cover the material on the surface of whichI .the grain of a cert-ain sort of wood shall lbe imitatedwit-h color szzficient to'produce the ground tint of .the wood to be imitated. After this coat of color has become perfectly dry I impress numerous4 small indentations on the whole .colored surface,l deep enough to pene-4 trate the coat of color and enter the surface of the material over whichthe color was laid on.

This maybe done by means of an instrument' provided with a handle, a, and a convex sur-.

face or surfaces, e d, at one or both ends, respectively, the said 'surfaces being covered with 1 j* a'uu'fmber of sharp metallic points and edges, -l fg,',which when pressed against the colored surface, as above, will leave indentations on said surface resembling in their conguration f the pores of the kindof vwood which the said points and edges were suitably constructed to imitate. .'From this it will be evident that different instruments with said points and edges differently arranged will have to be used for properly imitating var ious kinds of woods. An instrument provided with two printingsurfaces, c d, as represented by the accompanying drawing, may be used to represent the grains of two different woods.v It will also be understood that instruments of a different shape and construction (for instance.,I a roller with the points and edges arranged around its cylindric surface, said roller to be rolled across 4the colored surface) might be used for this purpose, and it is therefore not my intentention to coune myself to any Ipeculiar con'- struol'ion, of the instrument inl applying for4 Letters Patent on my'improved -mode of imi vtating grains of wood. When thewhole surface has been covered with these indentations, as described, the long veins are traced on the surface in darker color and in the usual man 'ner of whatis technically termed graining The darker color, as it is put on the surface, lls'the indentations, and thus-imparts to them the dark appearance of the pores ofthe wood to be imitated.- lhe work is then finished by putting on the usual coat or coats of varnish.

vIt will 'be seen that the size, depth, and :consequent darkness of the pores can be regulated by pressing the instrument (above described). more or. less hard against the colored surface. 4 y

Having described my invention, what 'Iv claim', and desire to secure by Letters Patent, 1s

The above-described inode of ,imitating the peculiar porous appearance ofthe grain of various woods on paper, leather, o il-cloth, wood, metal, or other suitable material, b vl iirst coveringthe material with a coat or coats of color and then (preparatory to the usual processoi' graining and varnishing) imprint? ing on the colored surfacefnumerous small indentations, resembling the pores of the wood to be imitated, by means of fa, suitable instrument provided with a number of sharp .points and edges, all as above" set forth. l i Y 3 FREDERICK DEGELoW. g
